Pulchrius and foedius look like neuter comparitive adjectives...but they are not, are they? Are they adverbs? It's just that one would have expected pulchre or foede - like recte and prave. Can anyone clarify what pulchrius and foedius are? Are they adverbs and (therefore) indeclinable?

Adrianus, this slightly throws my world into confusion. I wasn't aware: 1) that adverbs were declinable and 2) if they are I can't see why one would use neuter in this case. What gender are / would they be in agreement with...? Do you mean they are neuter comparative adjectives...? which would be -ius...??
